Things 21 & 22

I made a wiki that will serve as a group study guide for a test. https://discussion-zone.wikispaces.com/ So far the students have not added too much and one of them has gone on and erased everything! I like that everyone can edit the page, but it's hard not knowing who is adding (or deleting) what. I'm hoping it will serve as a study guide for struggling students, but we'll see. I think I prefer the blog because I know who is posting and when, but the wiki is good for an informal setting.
